Scalable multimode entanglement based on efficient squeezing of propagation eigenmodes
D. Barral, K. Bencheikh, J. A. Levenson +1
Continuous-variable encoding of quantum information in the optical domain has recently yielded large temporal and spectral entangled states instrumental for quantum computing and q…
Quantum state engineering in arrays of nonlinear waveguides
David Barral, Mattia Walschaers, Kamel Bencheikh +4
In the current quest for efficient and experimentally feasible platforms for implementation of multimode squeezing and entanglement in the continuous variable regime, we underpin a…
Versatile photonic entanglement synthesizer in the spatial domain
David Barral, Mattia Walschaers, Kamel Bencheikh +4
Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top b…
Sending classical information via three noisy channels in superposition of causal orders
Lorenzo M. Procopio, Francisco Delgado, Marco Enriquez +2
In this work, we study the transmission of classical information through three completely depolarizing channels in superposition of different causal orders. We thus introduce the q…
Coupling quasi-phase matching: entanglement buildup in nonlinear waveguide arrays
David Barral, Nadia Belabas, Kamel Bencheikh +1
Wavevector quasi-phase matching was devised in the 1960s as a way to boost nonlinear interactions with efficient quantum noise squeezing as one outstanding outcome. In the era of q…
Zero supermode-based multipartite entanglement in nonlinear waveguides arrays
David Barral, Kamel Bencheikh, Nadia Belabas +1
We show that arrays of nonlinear waveguides in the second harmonic generation regime are a promising source of continuous-variable entanglement. We indeed demonstrate ana…
